Zorluk: OrtaClimate, Weather Systems, and Monsoon of India

Arrange the following Indian cities in the correct chronological sequence of the normal arrival date of the South-West Monsoon, from the earliest to the latest:

  1. 1Thiruvananthapuram
  2. 2Mumbai
  3. 3Delhi
  4. 4Jodhpur

Cevap

The correct chronological sequence of the normal onset of the South-West Monsoon is Thiruvananthapuram (around June 1), followed by Mumbai (around June 10–11), Delhi (around June 27–30), and lastly Jodhpur (around July 5–8).
The South-West Monsoon enters the Indian subcontinent from the south and south-west. The normal onset date over the southern tip at Kerala (Thiruvananthapuram) is around June 1. As the Arabian Sea branch advances northward along the west coast, it reaches Mumbai by June 10–11. The combined branches advance across the Indo-Gangetic plains, reaching Delhi by late June (around June 27–30), and finally cover the desert regions of western Rajasthan (Jodhpur) by early July (around July 5–8).

Adım Adım Çözüm

1
Identify the geographical location and monsoon entry point for each city
Thiruvananthapuram is on the southern tip (Kerala coast); Mumbai is on the western coast; Delhi is in the northern plains; Jodhpur is in western Rajasthan.
The South-West Monsoon advances from south/south-west towards the north-west.
2
Determine the normal IMD monsoon onset dates for each city
Thiruvananthapuram (~June 1) < Mumbai (~June 10-11) < Delhi (~June 27-30) < Jodhpur (~July 5-8).
The Arabian Sea and Bay of Bengal branches travel northward and north-westward, reaching the extreme north-western parts of India last.
3
Arrange the cities from earliest to latest arrival date
Sequence: Thiruvananthapuram → Mumbai → Delhi → Jodhpur.
Matches the spatial progression of the advancing monsoon across the Indian subcontinent.
